Which Google Workspace add-ons make real money now?

Is there actually serious money in Google Workspace add-ons?

Yes, Google Workspace add-ons can still become multi-million-dollar software businesses, and the clearest money today sits in data automation, email, document workflows and specialized spreadsheet tools.

Supermetrics is the strongest example we found. The company began with a tool that pulled marketing data into Google Sheets, and founder Mikael Thuneberg has repeatedly described the launch of the Sheets add-on as the point when growth really took off. Supermetrics later expanded far beyond Sheets into data warehouses, APIs and marketing intelligence. Founder disclosures have put the business around €60 million in annual recurring revenue.

Talarian gives us another useful case because several of its products still live directly inside Google Workspace. Yet Another Mail Merge has more than 16 million Marketplace installs, Form Publisher has 24 million and GPT for Sheets has 7 million. In a founder interview earlier this year, Stéphane Donzé said the broader group containing AODocs, Talarian and the Revevol services business was heading toward roughly $60 million in annual revenue. AODocs contributes around $30 million, while Donzé said YAMM itself now generates roughly six times the approximately $1 million it was making in 2016. That implies a business around $6 million a year from one Workspace-born email product.

There is also a large middle tier. Coefficient was reported at $6.1 million in annual revenue in 2023. Coupler.io is estimated by GetLatka at around $1.8 million for 2025. SlidesAI, despite having 15 million Marketplace installs, is estimated at roughly $880,000.

Those examples give us a useful range. Google Workspace can produce $500,000-$2 million bootstrapped products, several-million-dollar SaaS companies and, in exceptional cases, businesses that eventually grow far beyond the Marketplace.

Business	Current Workspace footprint	Best public money evidence
Supermetrics	4M+ Marketplace installs	Founder disclosures around €60M ARR for the broader platform
YAMM	16M+ installs	Founder comments imply roughly $6M annual revenue
Coefficient	500K+ users cited by company	$6.1M revenue reported for 2023
Coupler.io	Hundreds of thousands of Workspace users	~$1.8M estimated annual revenue
SlidesAI	15M+ installs	~$880K estimated annual revenue

Why are Google Workspace install counts so misleading?

Google Workspace Marketplace installs are useful for measuring reach, but they tell us surprisingly little about how much money an add-on makes.

Google counts users who receive an app through an administrator alongside people who install it themselves. A company-wide deployment can therefore add thousands of Marketplace users at once. We also cannot see how many of those people opened the product last week, how many use it every day or how many pay.

SlidesAI shows the problem perfectly. It currently displays more than 15 million installs, yet GetLatka estimates annual revenue at about $880,000. Supermetrics shows a little over 4 million Marketplace installs today while its broader business has reached tens of millions of euros in recurring revenue.

The economics are completely different. A person might install an AI presentation tool, create two decks and never return. A marketing team may use Supermetrics every morning to update reports tied to millions of dollars in advertising spend.

Marketplace rankings give us a useful popularity clue. For money, we need revenue disclosures, pricing, usage limits, business customers and evidence that people keep coming back.

Is Google Sheets still the best place to build a profitable Workspace add-on?

Google Sheets is still the most convincing Workspace surface for building a paid business because companies keep forcing spreadsheets to handle work that stretches far beyond ordinary spreadsheet editing.

Look at what successful Sheets products actually do. Supermetrics moves marketing data into spreadsheets. Coefficient connects systems such as Salesforce, HubSpot and Snowflake. Coupler.io imports and refreshes data from hundreds of sources. Sheetgo links files and automates spreadsheet workflows. GPT for Sheets processes entire columns with AI. Mail-merge products use Sheets as the database behind personalized Gmail campaigns.

The common thread is already sitting inside the customer's spreadsheet. A sales team has its leads there. Finance has budgets there. Marketing has campaign data there. Operations has inventories and trackers there. The developer does not need to persuade the customer to rebuild everything in a new application before delivering value.

Google has also made Sheets much more capable lately, including native AI that can build and edit full spreadsheets. That raises the bar for developers, but it also confirms how much work companies want to perform inside Sheets.

If we were starting with one Workspace surface today, we would still look at Sheets before Docs or Slides. The best opportunity is increasingly a workflow around the spreadsheet rather than another way to format cells.

Are data connectors the best Google Sheets business right now?

Yes, data connectors have the strongest record of turning a Google Sheets add-on into a large recurring-revenue business.

Supermetrics built the template. Its original proposition was painfully simple: stop manually downloading marketing reports and copying them into Sheets. That small convenience became more valuable as customers connected more advertising accounts, added scheduled refreshes and started depending on the resulting reports.

Coefficient follows the same logic with operational data. It brings Salesforce, HubSpot, databases and other systems into spreadsheets and lets users refresh or push data without repeated CSV exports. Coupler.io has expanded even faster on the connector side. The company said it went from roughly 60 supported sources in 2024 to 78 in the first half of 2025, more than 240 by mid-autumn, and eventually above 400.

That trajectory tells us more than another install count. Connector companies keep adding integrations because every additional system broadens the number of business processes they can sit inside. Once a company builds recurring dashboards around those connections, switching becomes inconvenient.

The revenue also supports the thesis. Coefficient reached a reported $6.1 million in 2023, while Coupler.io is estimated around $1.8 million. At the top end, Supermetrics became vastly larger.

For someone looking at Workspace today, data synchronization remains the cleanest proven path from “useful Sheets add-on” to genuine SaaS.

How did Supermetrics become so much bigger than a normal Sheets add-on?

Supermetrics became a much larger business by using Google Sheets as its entry point and then following customers into increasingly expensive data problems.

The early product solved one task: pulling marketing data into a spreadsheet. Larger customers soon needed more sources, more destinations, scheduled transfers, warehouses, governance, APIs and better control over who could access what.

Supermetrics now sells an entire marketing-data infrastructure. The company's reach goes well beyond Sheets, and it says its systems process data associated with roughly 15% of global advertising spend. That is a very different business from charging someone a few dollars for a sidebar.

This expansion also explains why comparing Marketplace installs can fool us. Supermetrics currently shows more than 4 million Marketplace users, while some free or cheap utilities show several times that amount. The difference appears when we look at what an account can eventually become worth.

Supermetrics reached roughly €60 million in recurring revenue. The bigger lesson is the route it took: find a painful job inside Workspace, earn distribution there, and gradually own more of the surrounding workflow.

Does Gmail mail merge still make real money?

Yes, Gmail mail merge remains one of the most proven paid Workspace niches, with several products at multi-million-user scale and at least one with founder evidence pointing to several million dollars of annual revenue.

YAMM currently has more than 16 million Marketplace installs. Digital Inspiration's Mail Merge with Attachments has millions more. Mailmeteor is around 7 million. GMass has built a large Gmail-centered business as well.

The paid upgrade is easy to understand. Casual users can send a small campaign for free. Recruiters, salespeople, schools, communities and small businesses quickly hit sending, tracking, scheduling or automation limits. Those users have a reason to pay immediately because email is tied to something they are already trying to accomplish.

YAMM gives us unusually useful revenue evidence. Stéphane Donzé recently said the product was making around $1 million a year in 2016 and has since grown to roughly six times that level. That puts it near $6 million annually if we take his comparison literally.

The niche does have a natural ceiling. Gmail and Apps Script impose sending limits, while dedicated sales-engagement and email-marketing platforms become more attractive for sophisticated campaigns. Even so, a product can build a sizeable company long before reaching that ceiling.

Is document automation quietly one of the best Workspace niches?

Document automation is one of the strongest Workspace niches today because users repeatedly pay to remove paperwork that would otherwise consume real employee time.

Form Publisher now shows more than 24 million Marketplace installs. It turns Forms or Sheets responses into personalized Docs, PDFs, spreadsheets, presentations and Microsoft Office files. Document Studio has millions of installs and automates invoices, certificates, emails, documents and approvals. Portant has also built a business around creating documents from Google Sheets and Forms data.

These products tend to enter workflows that repeat constantly. A form response creates a certificate. A new customer triggers a contract. A spreadsheet row generates an invoice. A sales record becomes a proposal.

That repetition makes document automation much more interesting than a utility people open twice a year. Once the template, fields and approval process are working, employees have little desire to return to manually copying names and amounts between files.

Form Publisher is especially telling because Talarian has kept investing in the product alongside YAMM and GPT for Sheets. The same operator has spent years building businesses around three different Workspace workflows: sending emails, generating documents and processing spreadsheet data. That concentration looks deliberate.

Can a boring Google Workspace utility still make good money?

Yes, a narrow Workspace utility can still become a solid small software business when it fixes an annoying task with strong search intent.

Foxy Labels is a good example. The product creates printable labels from Google Docs and Sheets, has more than one million Marketplace installs and has accumulated thousands of reviews. Its paid offer has included a roughly $39 annual plan and a $99 lifetime option.

There is nothing trendy about printing Avery labels. That is exactly why the example is useful. Someone searching for a label maker normally wants to solve the problem now, and manually building correctly aligned sheets in Docs is tedious enough to create willingness to pay.

We should keep the likely scale in perspective. Public evidence does not show label utilities regularly becoming $10 million SaaS companies. They can still be attractive owner-operated products because development is manageable, acquisition can come from search and support requirements are relatively contained.

The profitable micro-SaaS opportunity in Workspace is alive. The giant outcome usually requires a workflow with more frequency, more seats or more room to expand.

Are AI spreadsheet add-ons still a good business now?

AI spreadsheet add-ons can still make money, but generic “ChatGPT inside Sheets” products have lost much of the advantage they had two years ago.

The demand is obvious. Talarian's GPT for Sheets currently has 7 million Marketplace installs. Another competing GPT spreadsheet add-on has passed one million. OpenAI's official ChatGPT integration for Google Sheets now shows more than 3 million installs as well.

At the same time, Google's native Gemini can build new spreadsheets, edit existing ones, fill data, create tables, analyze information and handle increasingly complex end-to-end tasks. Google has spent much of this year moving Gemini deeper into the actual spreadsheet rather than keeping it as a simple chat sidebar.

That leaves third-party developers with a tougher question: what can they do after everyone already has access to an AI assistant?

GPT for Sheets gives us one answer. The current product emphasizes bulk operations such as classification, translation, enrichment, scoring, cleanup and content generation across large numbers of rows. Users can choose different models and process repetitive tasks at high throughput. That workflow goes deeper than asking an assistant to write a formula.

This is where we still see room. A product that processes 50,000 leads, classifies a catalog or enriches thousands of company records can charge for throughput and automation. Another generic sidebar offering “ask AI about this sheet” will face brutal competition from Google, OpenAI and dozens of nearly identical add-ons.

AI spreadsheet product or threat	Current evidence	What it means
GPT for Sheets	7M+ installs	Strong distribution; increasingly focused on bulk workflows
Official ChatGPT for Sheets	3M+ installs	OpenAI itself now competes inside the Marketplace
Other GPT spreadsheet add-ons	Several have 1M+ users	Basic model access has become crowded
Gemini in Sheets	Native full-sheet creation and editing	Google now covers many jobs that once required an add-on

Are AI presentation add-ons getting squeezed by Google Slides?

Yes, generic AI presentation generators are in a much worse position now because Google can generate complete editable presentations directly inside Slides.

SlidesAI still has remarkable distribution at more than 15 million Marketplace installs. GetLatka estimates the business at roughly $880,000 in annual revenue, which would already make it a successful bootstrapped product. Plus AI has crossed one million Marketplace users and sells subscriptions to individuals, teams and enterprises.

The competitive landscape has changed quickly, though. Gemini can now generate a full presentation from a prompt, use Docs, Sheets, PDFs or old decks as source material, match the style of reference presentations and produce editable slides inside Google Slides. Google has continued adding these capabilities lately rather than treating deck generation as a side experiment.

A standalone tool needs a more specific reason to exist. Plus AI is already pushing toward that kind of differentiation with PowerPoint support, custom company templates, APIs and enterprise workflows. Those capabilities can survive even when basic slide generation becomes standard software functionality.

SlidesAI's 15 million installs alongside an estimated sub-$1 million revenue figure also gives us a warning. Massive curiosity around AI does not automatically create massive monetization.

What pricing model works best for Google Workspace add-ons?

Freemium still fits Google Workspace extremely well because users can experience the useful part first and encounter the paywall when their workload becomes serious.

Mail merge shows this clearly. Someone sending a tiny batch can use a free allowance, while a person repeatedly contacting hundreds of recipients needs more volume, scheduling, tracking and automation. The upgrade feels connected to usage rather than arbitrary.

We see the same pattern elsewhere. Label products cap free output. Data tools limit refreshes, connectors or destinations. AI products meter credits and processing volume. Document tools restrict the number of generated files or premium workflows.

The most attractive pricing grows alongside the amount of work being automated. Ten rows can be free; 50,000 rows cost money. One report can be free; continuously refreshed company dashboards require a subscription. A few emails can be free; recurring outreach becomes paid.

Workspace developers also collect payments themselves rather than through a mandatory Google revenue-sharing system. That gives them room to sell monthly plans, annual subscriptions, usage credits and enterprise contracts.

Can the Google Workspace Marketplace still launch a new business by itself?

The Marketplace can still deliver meaningful distribution, but a new developer faces a far harder discovery problem than the early winners did.

Supermetrics entered the ecosystem when Google's add-on gallery contained only a small collection of products. Mikael Thuneberg has described that exposure as a major growth inflection point. YAMM also arrived early enough to accumulate a huge installed base and thousands of reviews.

Today's Marketplace is crowded. Google says search takes popularity, relevance and user ratings into account, which naturally gives established products an advantage. A new mail-merge app starts against YAMM's 16 million users. A new presentation generator meets SlidesAI's 15 million. A new document tool meets Form Publisher's 24 million.

Successful developers these days usually add other acquisition channels. Search content, YouTube tutorials, templates, direct sales, integrations and partnerships all appear repeatedly among the stronger companies we examined.

Marketplace distribution remains valuable because the user is already inside Google Workspace and can install a product quickly. Depending on that listing alone has become a much weaker strategy.

Is security becoming a real advantage for Workspace add-ons?

Security is becoming a meaningful competitive advantage because serious Workspace products often touch email, Drive files, customer lists and company data.

Google requires additional verification for apps requesting sensitive or restricted OAuth scopes. Depending on the permissions involved, developers may face independent security assessments as well. That work costs money and time.

Established vendors increasingly advertise those investments. Talarian highlights ISO 27001 and enterprise controls. Sheetgo promotes SOC 2 Type II and higher-level Google security assessments. Plus AI advertises SOC 2 Type II. Other Workspace businesses emphasize limited data retention and tighter permission scopes.

For an individual consumer, those badges may barely register. A company deciding whether to expose Salesforce records, financial spreadsheets or internal Drive documents to an add-on asks very different questions.

This creates a useful filter. A clone can reproduce an interface quickly; enterprise security, audits and years of customer trust take longer. The advantage becomes stronger as the add-on moves toward larger companies.

Which Google Workspace add-ons look popular but make weak businesses?

Generic AI writers, basic formatters, simple file converters and one-shot content generators look much less attractive than their Marketplace popularity suggests.

The main problem is frequency. A user might happily install a tool to convert one file, generate one deck or clean one document. That creates an install without creating much recurring value.

Platform competition makes the generic AI category especially uncomfortable now. Gemini works across Docs, Sheets, Slides, Gmail and Drive, and Google's latest Workspace updates let the system carry out increasingly complex tasks across several apps. OpenAI is also distributing ChatGPT directly inside Google Sheets.

A developer entering this market now needs some workflow Google and OpenAI have little reason to commoditize immediately. Proprietary data connections, specialized compliance, industry-specific document logic, bulk enrichment, company templates and cross-platform automation are much harder to absorb than another text-generation button.

We would be much more interested in an add-on automating a dull weekly business process than one producing a flashy result people try once.

What do the Google Workspace add-ons making real money have in common?

The strongest Workspace businesses usually remove a recurring task whose cost is obvious to the person doing it.

Supermetrics replaces repeated marketing exports. Coefficient and Coupler.io keep business data synchronized. YAMM turns spreadsheet rows into personalized email campaigns. Form Publisher turns responses into finished documents. GPT for Sheets processes large datasets without making someone prompt an AI row by row.

Frequency is doing much of the economic work. A problem that happens every morning is easier to monetize than one that appears once every six months.

The better companies also tend to expand outward. Sheetgo connects Google spreadsheets with Excel, OneDrive, SharePoint and Dropbox. Plus AI works in both Google Slides and PowerPoint. Talarian has moved its spreadsheet AI beyond Google's ecosystem. Supermetrics eventually turned one Sheets connector into an entire data platform.

That pattern gives us a useful way to judge new ideas. The best Workspace add-on can start extremely narrow, as long as the underlying job is frequent and leads naturally into a larger workflow.

Could Google simply copy the best Workspace add-ons?

Google can wipe out a weak add-on category surprisingly fast, and the latest Gemini releases make this risk much harder to ignore.

Google Sheets can now build and edit full spreadsheets through Gemini. Slides can generate complete editable presentations using other company files as context. Workspace's newer agentic features can also pull information across Gmail, Drive, Docs, Sheets, Slides and Chat and then create finished work.

Those releases overlap directly with entire categories of third-party products.

The safer businesses own pieces Google does not automatically control: hundreds of external connectors, custom approval rules, sending workflows, specialized datasets, compliance layers, branded templates, multi-cloud support or integrations with competing ecosystems.

A good test is simple. Imagine Google makes its native AI twice as capable next year. If the add-on loses almost all of its reason to exist, we would be uncomfortable building that business today. If the product still has valuable data connections, automation and specialized workflow logic, the platform risk looks much more manageable.

Which Google Workspace add-ons make real money now?

The Google Workspace add-ons making the clearest real money today are data connectors, Gmail outreach tools, document automation products and specialized spreadsheet workflows; generic AI add-ons are already becoming a much tougher bet.

Data integration has produced the largest independently visible outcome. Supermetrics grew from a Sheets add-on into a roughly €60 million recurring-revenue company, while Coefficient reached a reported $6.1 million and Coupler.io sits around the seven-figure level according to outside estimates.

Email has also proven itself. YAMM has more than 16 million installs, and founder comments put its revenue in the neighborhood of $6 million annually. Document automation has huge usage as well: Form Publisher currently shows 24 million installs, with products such as Document Studio and Portant attacking the same recurring administrative work.

AI deserves a more selective conclusion. GPT for Sheets has 7 million installs and clearly found demand, while SlidesAI has 15 million. Yet Google's own Gemini can now build spreadsheets and complete presentations, and OpenAI has brought ChatGPT directly into Sheets. A developer starting today needs something deeper than model access.

So if we were looking for the Workspace businesses with the strongest economics now, we would focus on software that moves business data, sends or generates high-volume work, or automates a process companies repeat constantly. The Marketplace still offers exceptional distribution. The money increasingly comes from what the product owns around Google Workspace once the initial install is over.

Workspace niche	Evidence we found	Current read
Data connectors and reporting	Supermetrics at roughly €60M ARR; Coefficient at reported $6.1M; Coupler.io around seven figures	Strongest proven category
Gmail mail merge and outreach	YAMM 16M+ installs and roughly $6M implied revenue	Proven and durable
Document automation	Form Publisher 24M+ installs plus several large competitors	Very strong recurring workflow
Spreadsheet workflow automation	Multiple seven-figure businesses and large installed bases	Strong
Specialized spreadsheet AI	GPT for Sheets 7M+ installs, with bulk automation becoming the key use case	Attractive when specialized
Generic AI presentations/writing	Huge installs, including SlidesAI at 15M+, while native Gemini is moving quickly	Much riskier now
Narrow utilities	Several million-user products exist, often with simple paid tiers	Good micro-SaaS territory, lower ceiling
